could anyone please explain to me the difference between functions:
copystr() and copyinstr() ?
For i386 copyinstr is implemented in assembler. I can not read
the assembler code very well.
I tried to allocate a memory in space of user process using vm_map_find
and then with copystr() I could copy data between user and kernel
memory. copystr() seemed to be able to do the same what copyinstr do.
